| Lab 1.1.2 OSI Model review - Overview Estimated time: 20 min. Objectives: Match devices and terminology to the various layers of the OSI model Match OSI layers with those of the TCP/IP model Identify TCP/IP protocols and utilities that operate at each layer Background: This lab will serve as a refresher to reinforce understanding of the seven layers of the OSI model as they relate to the TCP/IP model. Focus is on where terms and devices fit in the OSI model. This lab can be a fun collaborative knowledge competition activity. Tools / Preparation: Create a group competition! Count off and divide into teams of 2 to 4 people each. Without looking at your notes or answers, see how accurately your team can fill in the OSI table in the worksheet. The team with the most correct entries (points) in the table at the end of the specified time (e.g. 10 min.) wins. If another team questions a term or table entry, they may challenge and receive the points if agreed upon by the review committee (made up of one member from each team). Before beginning this lab you should read the Networking Academy Second Year Companion Guide, Chapter 1 and chapters 1, 9 and 10 of the First year Companion guide. You should also review semester 3 on-line Lesson 1. The following resources will be required: PC workstation with Windows installed NIC installed and Cat 5 patch cable with connection to the Internet Browser software installed (Netscape Navigator 3.0 or higher or Internet Explorer 4.0 or higher) Sample networking items such as Ethernet and Token Ring NICs with different connectors (Coax, AUI, RJ-45) Sample Hubs, Switches and Routers Notes: Step 1 – The OSI model and associated TCP/IP protocol stack layers. Task: Fill out the following chart based on your knowledge of the OSI and TCP/IP models. Explanation: Your understanding of the OSI model as it relates to the TCP/IP model will greatly increase your ability to absorb and categorize networking information as you learn it. 1. Given the OSI layer number fill in the chart below. Compete with other teams if possible and try to think of as many protocols, standards, utilities, terms and devices as possible without looking at your notes. Note: TCP/IP layers will relate to more than one OSI layer. OSI model and TCP/IP Protocol Stack
OSI # | OSI Layer Name (and function) | TCP/ IP # | TCP/IP Layer name | Protocols, standards & utilities at each TCP/IP layer | Devices and Terms associated with this layer
